To all 'whom it concern.'

Be it known that I, FREDERICK S. .Epnn'rn a citizen of the United States, residing at `El1nira,in the county of lChemung and State of New York, have invented certain new and useful 11n irovernents in' Clutches, of which the lfollow ng is e specification.

This invention relates more particularly to improvements in clutches for motorcycles, whereby' the drivingI pulley, or Wheel, is thrown intoinr out 'df engagement with the y'engine or other `driving shaft; my objects lthe being to provides clutch operating inechn` -nisinlfree from end thruston the shaft and actuated by means positioned at the inward side tuithe pulley; lthat lto say, between pulleyand the engine vcasing cleo to provide e, simple and eileetivespring actuated clutch `for this purpose Whichwill tuke up the l,leed gradually when throwing in the clutch.` l 'I attain my objects by constructing the parts .of theelutch and opere-tingr mechanisrn in the manner lillustretedin thev ac` eompenying drawings, in whichM Figure l presents e longitudinal sectional vieW of the clutch es attached tothe end of s driving shaft; Fig. 2, e transverse section i Y on the line :c7- in Fig. 1; and Fig. 8, a longitudinsl sectional view of e di'erent form of the clutch.

` Iikmnmeml designate like parts in the several Views.

of the 'pulley is chambered,"nnd said chamber is inclosefd by e oep piece, which rides` on the bearing. The two bearings 4arend-y jnsted by a, cone 7, screwed upon the out ward end of the hub and locked in "plecegby Ythe oep screw 8, screwed into the end of the` huh Within the chamber in the pulley, clutch members, such as a plurality of friction disks 9 are mounted, said disks having alter- .neteI locking engagement Withthe pulley, and hub, in the usuel manner, the outward` end of the hub being preferably of hexagonal form, as shown at 2a in Fig. 2, toreceive the disks. A setting upl disk 10 engages' the outwnrd friction dislt,v and is provided with' e'central portion 12, positioned Speoication or Letters Patent. i A Application fried February 1G, 1911. Serial No.

This setting up disk is provided with e plurality of sockets 13, to receive springs i4, the outer ends of whichV are positioned in correspondM ing sockets in a disk 15, {it-ted upon the end with thedisk 20, which is slidubly mounted upon the hub und provided with diametricelly opposite grooves 21 to receive the ends of the tioned between the disk 20 end a. longitudinally movable thrust member 23, provided With an operating arm 24, from which connection is mede to` nn operating lever upon the handle vber of the motorcycle. This thrust member has e cem engagement with e stationair member 25 which-'is held rage-inst rotationV by means of an arm` QG,

vadztpted to be fastened to the engine casing, or other fixed support on the machine. The clutch members muy also be releasedV by holding ccm member 23 stationery und. rota'ting `cem'member 25. The inward thrust on this cem member is received on the in- Ward end of the hub through e; bull hearing et 27. As herein shown .the cam member is provided with e spiral, or screw' thread groove to receive a corresponding'internal thread on the thrust member 23.

To operate the clutch-reieesing mechenism the arm 24 will be turned in e. direction `to` move thethrust inembei.' 23 outward,

.thereby imparting outward movement to the thrust bar 16 through disk QG 19. The disk 10 will thereby be moved outu `Ward to compressthe `springs sind release the clutch members. Upon Srelensinggthe erm Z4 the' springs will et 'to push thedis'k 10 inward, seidinvvnrd pressure upon the disk .acting through the thrust rod 16` to slowly turn the thrust member 23 backward by reason `ofthe incline given to the cern pin 19. A ball bearing 22 is posi`.

parte. The clutch members lfire thus gradsv Y* elly set up-into gripping engagement.

While I prefer to construct the clutch pui-` ley in the mennen/above described, for the reasonA that it plces the operut ng arm of the pulley, thetis to sey, between thepulr,

This form of clutch is wn in Figi 3, and consists, as before, ofaflhollow hub 2a, adapt--v ed to be fastened upon the'end of the engine shaft, and having thel` driving pulley 3 mounted thereon by ball Ybearings at 4 and 5, a cap 6% for the clutch chamber bein mounted as before upon the bearing 5, sai

bearings being adjusted by a cone 7", Vwhich is locked in adjustment by means of a'capscrew 8. This cap screw'has an enlarged head provided witha chamber iny which a cam member ornut'30 is mounted, said member having a thrust bearing 81 between itj and the inward wall of the chamber, and'be ing held in placeby a flan ed ring-32,
